Allow a Manual “other” account

I use Chowbus Delivery, but I am unable to record the manual trips on the proper “account,” because you must choose from a limited list of providers. I record manually for everything (Doordash, Uber eats, etc.), so when recording for Chowbus, I chose a service provider at random to record my trips. I wish there was an “other” option where I can edit the name and type “Chowbus.” This can’t be too difficult, as I don’t link my accounts to the driver apps, regardless. Thanks! Ryan
