Acrobat pro DC template creation with multiple signature loop

Hello,

I need to often circulate a PDF form that requires a signature loop amongst 7 people (always same users and always same chronoligical order).

Each signator must: SIGN, DATE and CHECK either ACCEPT or REJECT before it goes to the next person.

I am the document iniator and I have Acrobat DC Pro to create the PDF but it is extremely time consuming to assign each feld individually to each user.

What would be the most optimized way to do this (I assume using a template) but where do I start, I can;t seem to find an option to upload or save such a template with pre-defined signature fields.

Lastly, when I assign a signature request to someone, they can only sign a specific area that I preselect from my PDF... I have a large area at the bottom of my form for "comments", is there a way to allow "ANY" of the 7 people in loop to add their comment if they wish to... I seem to be limited to only assign that option to 1 person while I would want to have that option open for anyone.

Thank you for your help with my issue.
