any way to automatically rename text fields?

Hi, I'm putting together an interactive form in adobe acrobat pro,
I used the wizard to automatically create things but it missed out on a whole bunch all over the place so I've had to create them myself.

The quickest way to create them was for me to set up a row and just copy and paste (or alt+drag) them to repeat.

The problem I ran into is they now all have the same name so when you fill in one it fills in them all.
Is there a way to automatically assign a new name to them now to save me having to go into each one and manually rename every single one individually?
(some pages have 50+ text fields, so it's not a simple process)

I'm new to creating interactive forms, and acrobat seems incredibly clumsy for setting up large forms.
Any help or tips to this end would be greatly appreciated, Thanks
