Allow registrants to change their registration details
Registrants could view their registrations and cancel them. But the edit registration details and options is still not presented.
There are many cases then this function required, started from typo to registration options.
At the same time not all administrators allow to edit registrations, it depends on many factors, the main it may affects costs.
Another case is adding / removing guests to existing registration, we have separate thread about this: https://forums.wildapricot.com/forums/308932/suggestions/8827063

An example we have for this need is on buying lift tickets. Initial the registrant might add a 5-day lift pass but things change and now they want a 6-day or 3-day pass. This now has to be handled manually. BUT, need to make sure the change flows to the invoice. We currently have a problem, if the original invoice is for $150 and the admin edits the invoice to raise the invoice amount to $300 but the invoice was already paid in full: the member can't pay this additional when they try. They get the message like: "the invoice is already paid."
