Going beyond the first 250 matching users during selection

Hello,
Is it possible to change the current limit of 250 users when using the "Select Users" popup in the "Client Access License Management" page?

In this scenario there are more than 250 users in the repository, and it is necessary to add a license to all of them.
When selecting "Show All" only the first 250 users are listed:
"Showing first 250 matching users"

The same issue appears when adding users to a new Project Area.
When performing "Show All" only the first 250 users are actually displayed.

Thanks!
Umberto
