Customizing "log activity" in HubSpot CRM

I am definitely for the idea of being able to customise activities. We’re trying to track aditional things like reaching out/connecting.seindgin messages on Linkedin and having to do it manually is taking up very valuable time form the team. Having an ‘other’ option that allows you to customise the drop down in the same way that you can for the ‘call’ options would be ideal.
