Yup, it's the same here,
my workaround is, if you then press mod source and another lfo, for example, you only have to navigate one or 2 sources up/down to select it.
Same for destinations that are not on the module front panel, click on the relevant section/item button, and you're already a lot closer.
Sometimes it selects a slot where the source is already in use, that's a bit annoying if you're not paying attention
