Mqtt sending multipel commends to IRTX

Hi All.
I just want to find would I do the following.

I want to use the espeasu irRemote.

but my deciding question is.
if I say want to send to my satellite decoder a set of commands
example to go to ch 117 . how would I do that ?
would it work to do it .

I will be using Mqtt to send the commands. have that sorted. just that I am not sure how to do the set of commands .

want to create buttons that would never to a channel and once pressed the commands need to be sent to the equipment .
