Thunderbird - Adding mixed AND/OR Message filters

[Meo]

Currently, the Message Filters feature allows only for AND and OR with "Match all of the following" and "Match any for the following". It would be good to have an option to add more advanced filters, to be able to perform actions like for example:

Match all of the following (AND):
From is "example@example.com"
Subject contains "sentence A" OR "sentence B"
...etc

It can be done by making separate filters for each case (one for sentence A and one for sentence B), but it makes filter management tedious from the perspective of end-user, when setting and especially updating groups of filters containing many rules. Matching multiple messages via a single filter with mixed AND OR would improve the readability of user-created filters and make it easier to manage the filter list.
