I was asking the same question on TYPO3Slack and the Powermail Git, but no answers so far.

TYPO3 v10, Powermail V8.5.1 (will be upgraded soon, I promise ;))
Is it possible to use a field multiple times to get more than one receiver? The Predefined receivers example works so far, but I was wondering if it is possible to do something like this:

emailA = CASE
emailA {
    key.data = GP:tx_powermail_pi1|field|fieldA
    12345678=TEXT
    [email protected]
    default = TEXT
    default.value = [email protected]
}

#now checking the same field again:
emailB = CASE                            
emailB {
    key.data = GP:tx_powermail_pi1|field|fieldA
    key.stdWrap.crop = 3 | | 0
    123 = TEXT
    123.value = [email protected]
    default = TEXT
    default.value = [email protected]
}

# now make a list of mails to be sent
plugin.tx_powermail.settings.setup.receiver.predefinedReceiver.receivers1.email = {emailA.value},{emailB.value}

The code is just a mockup and does not work. But would it be possible?
