1Password 8 date and time formats

For someone who grew up in Britain and now lives in Germany, having a choice of date format is vital. There are two formats I use:
DD.MM.YYYY (common in Europe, note we use periods "." instead of slashes "/"
YYYY-MM-DD I use this format for filenames and anything that needs to be sorted by date. This is the most logical format that I believe is standard in Japan.
MM/DD/YYYY is the American format and the one I hate to use. It is confusing and neither sortable nor logical.

For 1Password to not support something simple like this, surprises me. If I had known this before switching, I would have looked for a different password manager. The fact that people have been asking for this for months and they even release version 8 without fixing this, does not give me much confidence in the company's ability to listen to their customer's needs. If there is not some sign of them actually fixing this, that should not be that difficult, then I will have to consider other password managers. I use dates too much for this to be acceptable.
