In MSSQL Management Studio, is there a way to view/set extended properties on a stored procedure parameter (not on the procedure itself)?

Parameters are nodes in the Object Explorer tree, but there is no Properties window on a parameter that I can see. On table columns, there is one.

I know I can view/set/delete them with TSQL procedures, sp_addextendedproperty and the like, but are they exposed in the GUI? “No” is an acceptable answer.
