Image in the Notes field of a transaction

Is it possible to include an image in the Notes field in a transaction? My use case is that I want to include a screenshot of some supporting data for a given transaction to help for tax purposes at a future point.
Alternatively, an ‘Attachments’ field could serve the same purpose an allow people to attach supporting documents.

Currently not, as that requires handling of file uploads (and their proper encryption).

But it’s a good idea for a proposal - I’m moving this to proposals
