Inclusion of covariate to dependent trait while calculating BLUP values

[nivelive]

I want to include Anthesis silking interval (ASI) as a covariate to grain yield while calculating BLUP values and plotting them.
gamem_met(Data, env = Loc_Code,
gen = ENTRY, rep = REP,
block = BLOCK, random= "gen", prob = 0.05, resp = "Grain Yield", verbose = TRUE)
How to include covariate ASI in this code

There is no current way to include covariates for computing BLUPs in metan. You can only analyze both traits at once using, eg., resp = c(GY, ASI)
