As a user, I would like to be able to search multiple Tests at once on the "Add Tests" screen

Currently, when adding existing Tests to a Test Plan, a Test Set, a Precondition or a Test Execution through the UI (Tests > Add Tests > Existing tests), it is not possible to search for multiple Tests at once using the Select tab on the Add Tests screen:

Searching issue by issue is okay:

But searching multiple issues at once does NOT work (either with spaces, commas or semicolons):

However, this was possible in Xray DC, and it is a useful feature when copying lists of Tests directly from a spreadsheet and adding them in bulk.

So as a user, I would like to be able to search multiple Tests at once when using the Select tab on the "Add Tests" screen.
