Modifying existing bam header line

[rickymagner]

Hi, is it currently possible to modify an existing BAM header line? There's the from_template method. But once you have your template header, e.g. read from a file you want to slightly modify, it seems like you can never remove any lines from it. There's the push_record method, but nothing that seems to allow for editing/removing any records.

Am I missing something? If not, is it possible to add some functionality like header.clear_records(b"RG") etc.?
