LSMW for MRO rev using Installation and schedule MR date

Hi Experts,

I have list of installations and corresponding Schedule MR date which I want to reverse , I tried using LSMW and recorded EL37 TCODE but in the recording it is not capturing 2nd screen fields because of which it is not working.

Any solution for this or alternate solution for reverse MRO for 1000+ Installations (I can not use MRU because I do not want reverse all MRO for a MRU)

Regards

Manoj
