Panadapter - Set SDR++ to Rig's 1st IF

[gbeyer3]

Hi, I'm planning to connect my rig to an RTL-SDR/computer (linux) to create a panadapter for my radio. I need to set the software to my FT-950's 1st IF, which is 69.45MHz. Is there a place I can set this in SDR++? As this is an edge case, if the UI doesn't support it, I'm willing to tweak a config file if necessary. Thanks much!
