Request - ground air conditioning?

Would it be possible to have a ground air conditioning unit to connect to the aircraft along with the GPU, please? An example seen here at CLT in 1989:

Thanks for considering!

Is that air conditioning or an air start unit? Looks like an ASU to me

@dadgametime There is only one ground connection on the F28 and it can be used for both air conditioning and engine start, regardless of what kind of GSE that hose may or may not be plugged in to.
