Complex PDF Issue

Hi there, hope everyone’s well. I’ve got quite a complex issue on my hands, so any support is appreciated.

I’m trying to create a pdf document that I can use as a template, have the ability to cut and paste unique text into the document. All with the hope of making this as efficient as possible for large scale file producing.
 

There have been a few issues I’ve run into because of this:

• My acrobat is incredibly slow, significantly more so compared to photoshop and illustrator.
• When in acrobat I can’t seem to edit the copied and pasted text format i.e bold, italic etc.
• I have these drop down option boxes (1-5 answers), however when I enter the answers and go to print, it clears the answers. (Acrobat online works if I share the document to my self and access through the link, but that’s quite time consuming.) 
• Due to it being unique text I’ve been trying to figure out how I can have text box reflow. So if there’s too much text, a “new” text box is made on the next page in order to fit all the text. (But that seems to be an impossible problem to solve.) 

I’m sure I’ve encountered other issues but can’t think of them right now, regardless, any help would be hugely appreciated,

Cheers
