Level 53 HOs on Brainstorm

[Ukase]

Just a QoL request. Made a build to test on Brainstorm, and apparently you can't get via custom level a level 53 HO. It just gives you a 50. Which, as we all know you can simply combine 3 more to make it 53. Well, this particular build is using a ton of HOs, so it's taking some time. It'd be nice if the 53 HO were an option. Obviously, just a QoL ask. No idea if it's impractical or not in implementation.
