Here's one way you can get close to your previous setting.
Correction: Here's one way you can check ride height without influence from other corners.
For example, let's measure the rear end height. Disconnect the rear sway bar drop link to disable any side-to-side influence. Jack up the front of the car and support it exactly in the middle of the suspension crossmember. If you can get to this point, you have now eliminated any influence the front corners have on the rear end corners. Instead of a 4-legged stool, you now have a 3-legged stool with each leg more independent from the others. If the RR and LR are uneven, it's because of their individual height settings and not because of any influence from the opposite front corners.
Ditto for the front.
I have a corner balance worksheet on my site if you're interested.
