In our homebrew particularly, I have a level 1 rogue, with the intention of going to Arcane Trickster at level 3. For the homebrews' sake and the backstory, our DM allowed me to take my cantrips already, but DnD Beyond does not provide the Spells category as an option for Level 1 Rogues. Being able to modify and tailor that would be very helpful.

Several ways around this.
A custom magic item with the spells is the easiest way. I believe you could accomplish the same thing with a custom background.
