Because that's exactly what I want to achieve: Change the filler bytes
between two segments, because these are "wrong" (i.e., not conforming to
the original ROM).

My only other solution to this would be to split the memory sections
into two, each with different filer.

No, it will not change the length, only the filler byte between them.

Perhaps my wording was misleading? With "count", I did not mean to add
exact filler bytes. I only wanted to say the filler bytes at the end of
a segment _get_ the defined fillval of that segment.

How can I change the value of this "something else" without defining a
second memory section?
