Propose time - multi calendar links

The propose times feature is really valuable, but for us to use it we need 2 things:

1: We need an easy way to insert calendar links for other users (without copy/paste)

2: We need to be able to create links to a booking page that combines calendars for several users, so that the lead can book a meeting based availability on a "shared calendar".

This would allow us to remove Calendly from our stack and rely on Pipedrive instead.
