I need this a lot too, in my case, i need to copy a property from the parent to child company that tells my support team how they should attend these companies.
The ability to copy properties automatically from parent to children companies would be super helpful!
This would cut out a lot of manual work for us, it is definitely needed!
This is definitely a requirement, surprised this can not already be done.
We need to sync company owners between parent and child companie, as well as various other properties.
Frustrating that this is not yet possible.
Great idea! This would be a very valueable addition to managing large and complex company ecosystems. The current parent - child functionality would immensly benefit from this!
Absolutely agree that this is necessary.
Without it, the parent-child association is pretty much useless.
Would love to be able to automate property updates from a parent company to the children underneath it.
We need this too badly.
yes - this is a critical feature for consistent database management.
Yes, this is critical. Please make this happen.
I need this, please!!!
Please please please make this happen. We have customers with multiple branches, depending on their situation it may be that one or more sales people will need to service the account. It would be great to have 1 parent landing page for the company, and child pages for all branches.
Agree with others that this is a critical feaure to support - child companies need to be able to ‘inherit’ parent company properties for various reasons. The entire handling of Parent/Child Company relationships in HubSpot should be looked at b/c it is not very robust at this time. We are migrating from SFDC to HubSpot and this is one area where users are frustrated with lost functionality.
+1 for this functionality
We desperately need this functionality!! We too need to be able to create a workflow that updates the owners of child companies when the owner of a parent company is added/updated.
Strong upvote for this idea - spent ages looking for this functionality because I couldn’t believe it wouldn’t already exist!
Really, really need this to be developed.
Need this stat, please 
Please implement this! Severely needed.
I need this a lot! I need to copy the owner of the parent account to the child account. Thanks for your help
How is this idea this old and still not done? Very much needed.
