Yea but to get the IVs to the parent is hard isn't it?
Just catch a copy of the Pokemon you want to breed with at least 31 IVs in a single stat or 2 & then breed it with another pokemon that you either also caught with at least 1 other 31 IV stat or just another pokemon at all...Once you get that IV or 2 onto the baby Pokemon, either repeat the process but this time using the baby pokemon as 1 of the parents & then proceed to soft reset until the IVs come out the way you want them or just stick with the Baby Pokemon as is...
To answer your question, NO it is not any harder to get the IVs to the parent if you breed for them first, then use them to breed the pokemon you will eventually use or whatever...
When breeding, get the moves you want onto the baby pokemon immediately without thinking about anything else, then work on Nature, & finally IVs...
