FVWM: Changing fvwmpager options on the fly

[Elliot Sowadsky]

Is there a way to for instance change the font of the pager label
(to/from none) after it's started?

I only want to display the label on certain desks.
My other option was turning Title/NoTitle, but that changes the pager height.

Using 2.5.13

Thanx
