Just to check: G Maj or G7?
Truth be known, in all my years of playing, I just cannot do a clean G7. Of the guitars I have, the Tele is the only one I can do a G7 at any reasonable level due to a more comfortable neck radius.
The point is; we all have 'those chords' and every single guitar player has a way to cheat.
With that said, since I have been trying to get that pesky G7 under control, I've been just fretting the chord and strumming it and seeing how long I can strum it clean. One chord and a bunch of strums. Keep in mind, I've been playing a good long time and most things don't completely get the best of me. However, my hand is what it is and that G7 chord is taking a bit more work. Like you, I need that chord to work. Some of the songs stuff I've been working on sounds better as a G7.
So, helpful? Who knows...... Good luck though!
