No, but there is way to get what you want if you always want to save
HTML entities to a separate file.

Kind of.  I'm sure the Mozilla folks will probably call it a limitation.
It should give you a choice.

I think most of the popular GUI MUAs auto set it by some arbitrary
criteria.  I would guess that if the media-type can be rendered by
by the MUA natively, they use "inline".  If they cannot, they use
"attachment".

I do not know if the popular GUI MUAs give you the option to choose.

Now, if you always want to have HTML entities saved to a separate
file, use a different filter:

<MIMEFilters>
text/html; m2h_external::filter; mhexternal.pl
</MIMEFilters>

The m2h_external::filter is the main filter for saving an entity
to a separe file.

CAUTION: The XSS issue I mentioned in a previous post still applies
since m2h_external::filter save the data "as-is".  Make sure you can
trust the posters to your list.
