On my drawing template, I have a custom property with value \\\$PRP:"Date"

Sometimes I want to hide the date, so I blank the property, set it's value to " " (space).  This works fine when manually editing the custom properties inside Solidworks.

However, when I try to get EPDM to blank that property, it does not work.  It blanks it in the datacard, but does not push the blank into the solidworks file.

When I rebuild, the datacard updates to match the evaluated value of the custom property ("01 jan 01").

Its like there is a safety built into EPDM to not overwrite any custom properties containing \\\$PRP... =/

Any ideas for how to blank this property with EPDM?  Thanks!

Also -

Curiously, if I used EPDM to set the property to \\\$PRP:"Date", it shows just like that in the datacard.  And it can be overwritten by EPDM.

But after solidworks rebuild the datacard updates to evaluate the \\\$PRP..., and then EPDM can't overwrite it again.
