Hi @napsternxg, can you let us know if you are still working on this so we can update our project board? Please just notify us the status by Friday April 8, no worries if you are not finished but intend to work on this. Please either ping me here at @hakunanatasha or ping the discord admins (with @admins)

[napsternxg]

Hi @hakunanatasha yes I plan to work on this over the weekend.

Hi @napsternxg thank you for letting us know! Ping anytime if you need help and looking forward to that PR!
