Homebrew overhaul - Grim Hollow Fix?

Is there any current expectations to allow homebrew to be more expansive on what can be added? Currently Because Ghostfire Gaming/Grim hollow hasn't manually added it like a few other things within the game such as the Blood related subclass and feat options, I've had to Manually add the Transformations into the List and because of the current setup of the Homebrew System, I'm having a hard time setting up, Related resistances, and benefits, and downsides of certain feat choices within those transformations, as example Aberrant Horror is currently my largest struggle to work on transferring the content to DND BEYOND player use for those within my Grim Hollow focus Campaign. I'm still relatively new with the current version of the Homebrew system and because of Query issues I can't seem to tackle, it seems to almost break the Homebrew make of the Transformation entirely.

While I would normally make this request directly to them I figured if other people have had similar situations where Content given access by DND Beyond Purchased content are not properly operated within the app/website yet. That maybe you've figured the problem I cannot currently get through.

To Repeat again to the Developers of both DND BEYOND and GHOSTFIRE GAMING, I am not adding this content to circumvent the cost, or to bypass payment. As I Have bought Both the Grim Hollow player Guide, and Grim Hollow Dungeon master Guide, along with the Lairs of Etharis and would love to share more content from the books I've purchased with my players but cannot currently because of both currently no additions made into the App/website to include them, as well as fix Blood magic within the selection.(Rogue - Blood Thief unable to properly equip blood spells etc.)
