Hi @Yoshi ,
We have solved this problem through our HubSpot app, CloudFiles. It looks and feels exactly like HubSpot Attachments but when you upload a file, a link is generated. You can activate/de-activate this link, put hard & soft ID validation, do time tracking, integrate with workflows etc… all in the context of your records. It is an enhancement over the HubSpot Documents tool.
We plan to launch it in March and are looking for prospective customers for feedback.
If you like, you can try out the app from HubSpot Marketplace.
