Just thought of this. The way I make my E7 chord shape from Dm to E7 is

1st string E – open

B string 3rd fret D note’- you don’t need to move this finger from it’s Dm fingering, I make my Dm with the pinky on this string/fret and just leave it right there for the E7 chord.

Open G string- G

2nd fret D string -E

Basically just those 4 strings make up this fingering of the E7 chord.
