Make a multi-encrypted message look like a single-encrypted message

[esskar .]

Hello there,

i have a message that is encrypted to with multiple keys,
so PgpEncryptedDataList contains more than one PgpPublicKeyEncryptedData
packages.

Before I distribute those message to the recipients I would like to remove
all the PgpPublicKeyEncryptedData packages that do not match the recipient
keys - so, the receiver will not see any additional encypted data.packages,
only the one he should care about.

Is there a easy way to do data kind of redecoding? Examples maybe?
