keep file selected after em_command

[nsp]

I have em_command(s) which change file size and date, i'm using date sorting. If i select my files and click on a button launching em_xxx, the file are processed but not selected anymore.
How to keep file selected after processing, I'm looking for an option/toggle working with all my command without changing them.

You can use a combination of commands:
cm_saveselection,em_command,cm_restoreselection

cm_saveselection,em_command,cm_restoreselection

Yes i know about save/restore commands but i do not want to alter menu and bars to have save the selection before any click.
I could have a cm_restoreselection but i miss an automatic save selection flag.

Rename the existing command to em_command_old. Create a new one with the same name (em_command), which consists of the combination:
cm_saveselection,em_command_old,cm_restoreselection.
