Entering Credit Spreads

I’ve just become a system vendor on here. I’ll be trading option spreads, and need the ability to enter them as credit spreads… I didn’t see that anywhere on the C2 trade screen. Is this possible? For example:

Buy To Open - SXMFR (SPX JUN 1590 Call) 100

Sell To Open - SXMFP (SPX JUN 1580 Call) 100

Credit spread: .45 or better.

Thanks in advance.

I think you’re SOL, I’ve never seen a way to do spreads.
