Using Text Variables to get target SHEETNAME

I have a clunky way to achieve what’s in the title. I create a dummy symbol to which I give an appropriate reference - like RDG for say ‘Reference Design Guide’. I place that non symbol off page but in the sheet where the detail is available. I can however then reference that non symbol in a text field in another sheet to produce something like ‘See detail in sheet ${RGN901:SHEETNAME}’. That’s works well for the one of two occasions I want it. I’m now doing a summary sheet where I may need more than I care to create in the local project library symbol file. Is there a better way to achieve this that I’ve missed along the way?

Thx
