Hi all,
I'm trying to create a custom property that has a drop down list of all server storage closets that once selected would recognize the building that it's located in as well. I got the building drop-down list made but that was after manually adding 178 values to the drop down list.

Now for the closet list I have ~700 records, so manually adding them would take an eternity. Is there a way to import a list from excel and have it come up for the drop-down list? I tried the 'Import Values' button but am sort of stumped on this part:

What made sense to me was that the Closet column would import to 'Closet' & then the OID would match to the proeperty 'Building' thus making a logical connection but I do not see it in the Orion Database Column list. What could be done to make this work out, if possible?
Any help is appreciated, thanks!
