Custom Variables and Keywords

It would be good to be able to set a custom variable or keyword for naming in export, or burn in window.

I use reversed date method ie '20231110' as the dating method for naming files on export. It would be good to be able to set up some custom variables for this.

Also, the ability to change the CASE of the variables used. Upper or lowercase.

+1 to case - maybe as a user preference? I’ve worked in places with different internal case formats and it always takes a couple attempts to get it right.

I suggested %Year, %Month, and %Day in this thread for custom date arrangements. viewtopic.php?f=33&t=184209

I wonder how custom variables could work/be implemented? Maybe a user/project preference for custom metadata, so it'd ask for "Parameter Name" and "Variable Name"?
