[Orgmode] Shortcut for complex searches

[Alessandro Pacaccio]

Hi,

I need a list of TODO items that match a given tag and are not scheduled after a
given date.
I use the C-c a M shortcut with the following search string:
+mytag+TODO="TODO"-SCHEDULED>"2000-01-01"

My question is: as I frequently use this search, is it possible to configure the
command in the org-agenda-custom-commands variable?

Thank you in advance.
