How do you give Ferroseed both Leech Seed and Knock Off as an egg move? (Pokemon SW/SH)?

Trying to make a competitive Ferrothorn set with Leech Seed/Knock Off/Gyro Ball/Spikes with Sassy nature. However, Leech Seed and Knock Off are egg moves for Ferroseed, and while scrolling through the egg move page for Ferroseed I saw that no parent pass down both Leech Seed and Knock Off. Is there any way to remedy this or am I stuck with one of the two forever? (Please note that I am playing SW/SH and I have the DLCs)

Luckily for you, there’s a new feature in SwSH just for this situation.

First thing you need is one Pokemon with the first egg move and another Pokemonof the same species (evolutions or pre evos don’t count)with the second egg move. For the one you want to learn the move, you need to delete one move so there is space for the one to be learned. Then put both in the daycare. I don’t know if you have to wait a bit for the move to be learned, but you don’t need to wait for an egg and they don’t need to be different genders, as long as their the same species and one has an empty slot.

Alternatively, just have the mother have the first egg move then breed with the father with the second egg move, for example for example tangela with knock off and ferrothorn with leech seed.
