XK99 Variants

Hi,

I want to change one of my existing variants in XK99. Let's say variant "PAYTERMS". This selected LFA1, LFB1 & LFM1.

Now I want to remove LFM1 data but don't want to change anything else. Does anyone know how to do that?

At the moment my only workaround is creating it again without LFM1 and then overwrite the existing variant. But in doing so I am losing all the selections I've made.

Thank you!
