Email ###VAR-### setup in dragscript

I’m using a variation on the perpetual dragscript. I’d like to add in some more data to my startup email to include the key timings/schedule for the night and ideally information on the targets that will be being imaged.

I’m guessing I could perhaps use a string or two to add that information and then use the ###VAR-### within the email action. Not sure how to add those key timings to a string (timings are set by astronomical dark minus a value) nor if one can call up info from within a sequence (such as the target name, ideally the flip time, etc.) and include in the email?

Has anyone implemented anything like this?

In the perpetual official DragScript you can found example of using of ###VAR###
