Additional Payment services and group integration

Ability to add new (and multiple) payment services particularly for QR code payments.

Preferably a public link from a photo hosting site (e.g. google photos) so the user hosts the file themselves

Ideally the user sets the name for the payment services instead of being forced to choose from possibly limited options.

This would then appear on another tab in the groups (i.e. ‘payment methods’) where others in the group can check how a particular person wants to be paid if they have multiple online banks with different QR codes for each.

The payment methods can be shown as a list set as a hyperlink (the name of the link is what the user set on the 3rd bullet point) pointing to the link they provided or alternatively have a preview function (hover or otherwise) for each payment method, if possible

Currency selection for each would be nice, in instances where the user has multiple banks across countries (and avoiding forex fees)
