--reml to loop over multiple phenotypes?

Hi there, I hope you are well. I am interested in estimating SNP-h2s for all expression levels in an eQTL dataset. If it's easy, would you be interested in implementing the ability to loop over multiple phenotypes (--mpheno args) one after the other? Even doing all the computation over again each time, it will save tremendous time to avoid reading the GRM..

Thank you!
