Dry run from UI

Hi, before executing a backup I am used to run a dry run and read the files are going to be changed.
I’m looking for this possibility from the User Interface.
I haven’t found anything except the possibility of enabling/disabling the flag inside the profile configuration.
I also tried to clone the profile and having a second one with the dry-run flag enabled, but during the execution I get some database error, maybe is not possible to have two profiles on the same database.

any help about the implementation of “dry run execute” ? thanks
