Help on concetration slots

[Wiking]

Hi

I play a troubadour and I often use spells that use concentration (con)

My charm spell use 5 con. When I'm in a dungeons and need to cast charm, I'm trapped with all my 5 con allready full. I haven't time to cancel them all and then cast charm with a aggro mob after me

Is there a command to unload all spells in con slots with 1 button press?

And, could I make a macro, that loads ex. spell 1, 3 ,5 .7 = 5 con slots at 1 button press?

Hope you understand what i mean
