Policy parameter drop down menu issue

[quinnwd11-cmd]

For the drop down option of a policy parameter it requires you to separate the options you want on the drop down menu by a comma and a space. However neither commas nor spaces are able to be typed in the options box. The only way I found to insert a comma is by typing all the options in one word (eg. MondayTuesdayWednesday etc.) and moving the insertion point between the options before placing a comma, which also automatically placed a space.
