"payment medium" on in F110

Hello experts,

When running the TCODE:F110, I would like to know if there is any menthod that I can only set the "payment medium" automatically on in the popup screen after I click the "payment run".

Now I using the TCODE:SHD0 create a new variant for F110, using this variant, the "payment medium" is automatically set on in popup screen after clicking both "proposal‘ and "payment run".

Thank you very much in advance.
