I am adding a note to call out a slope for drainage and want to include the item number and have it reference the correct item number automatically.

After doing some searching I found out how to put custom properties into a note by using \$PRPWLD. I have tried it and it works well for the items in the table that you can manually change by typing like \$PRPWLD:"Description" or \$PRPWLD:"Material". I have not been able to figure out if it is possible to do this for the item number. If so, what is the expression \$PRPWLD:"xxxx"?
