When i use linear transponders (inverted) i have to adjust RX until i find a signal and then adjust TX the opposite way (or the same way if its not inverted etc) so i can tx and hear the signal where i am.

Can a function be included where up and down link are "tied" to each other when using linear transponders or something?

It looks like you are tuning the frequency in a wrong way. When you tune as described in the Frequency Scale 
and Frequency Control sections of User's Manual, your RX and TX frequencies stay in sync.

I will test later with an inverted band in sdr window and see if rx and tx moves in + and - opposite of each other, looks like ill have to have sdr window by itself solely for moving the box for easy simultaneous tuning of both frequencies.

forgot to report back. dragging the box in wide waterfall window does move up and down link where they need to go respectively.
since i use sdr on if tap i only use waterfall window for adjusting frequency and then i see signals move on sdr program. i do need to turn sdr on in skyroof for waterfall window to work (red light since sdr is used by HDSDR), luckily it doesnt need actual sdr to connect before populating waterfall with sats.

only thing left to say is what others have said about limited range on how much you can move frequency up and down.

- the frequency scale with satellite labels and green box dragging / mousewheel tuning is supposed to work even if SDR is not enabled, or even defined. If this does not work for you, please provide the details
- limited range? green box tuning allows mouse tuning across the whole transponder segment. Please explain what you mean by limited range.
