Sort Blocks by date in the panel

I would like to sort the blocks in the panel by my own date fields “from” and “to”.

I tried to sort the blocks in my site.yml with the following:

    fields:
      munichBlocks:
        type: blocks
        label: Ausstellungen München
        num: '{{ page.date.from("Ymd") }}'
        fieldsets:
          projects:
            label: Projekte
            type: group
            fieldsets:
              - project-munich

the block “project-munich” has the two date-fields and I would like to sort the blocks from the newest to oldest.
My project-munich.yml:

name: Ausstellung München
icon: page
fields:
  exhibitionName:
    label: Ausstellungstitel
    type: textarea
  from:
    label: Startdatum
    type: date
    default: today
    display: D.MM.YYYY
  to:
    label: Enddatum
    type: date
    default: today + 1day
    display: D.MM.YYYY

I don’t think this is possible, there is no sort property like for the structure field, for example. Usually, your use case with only one block type would probably be better off in a structure field where you have the option to sort items. After all, the blocks field’s main purpose is more a WYSISYG experience, rather than a structured data input.

Okay, thank you anyway!
