Hi again @Mohamed_S.AboHoussie,
I am unaware of any Qiime2 script to make manifests.
Unfortunately, I think this is where learning some basic coding comes in. I have written my own Python scripts to make my manifests when datasets are large and this is probably your best bet. If you are more proficient in R then obviously would use that.
Alternatively, you could searching the forum for "make manifest" as some people have shared their code, for example here, here or here.
best of luck!
