Multi select on page 1 AND 2

Hey there,

i want to build up a list of dataset pairs out of 750 files. For that i need to multi select all of them. Here comes the problem.

The history only shows 500 files at one page, but i want to select all of the 750 files at once. Wheen i go to the second page after collecting the first 500, they will just be discarded out of my selection.

So the question: Is it possible to increase the ammount of shown files in the history from 500 to more?
Or: How to i multi select files from page one and two?

Thank you alot

Welcome!
I got no 500+ datasets collection here to test, but
Does the limit happen if you build with operations on multiple datasets button?

Also, can you generate collections of 500 datasets and then Merge Collections ?
