I understand your issue. It’s actually something already discussed and in the works for Catalog 4.0
Right now, Catalog 3.x needs to get all the kinks ironed out. Once it’s done, there will be discussion for creating a single catalog with all the mods available for separate downloads.
In the mean time, you can always unpack your current .iros and manually place your options in your game folder. I suggest backing up your data folder before doing so.
