help with bind for throwable weapons

[d3vin]

i have this bind

 

bind q weapon 10

 

to toggle through the throwable weapons but it only works when i have the thermal detonators (round things, like grenades). if i have trips or the det packs hitting q any amount of times wont bring up the trips or det packs. if i then went and picked up the thermal detonators, i could use q to toggle between all three

 

is there a way to have it so i dont need the thermal detonators to use the other throwables??
