You're probably solving the wrong problem -- the mail client really
ought to be able to process 300+ messages.  It may be a better use
of time to fix that than to torture dovecot to give you what you want.

You can try using a plugin to define a virtual INBOX

 	https://wiki.dovecot.org/Plugins/Virtual

with search/selection criteria to limit the number of messages.

You can also try some LDA script (e.g. procmail) hackery to create INBOX
volumes of 300 messages, then do some shuffling around when the INBOX
gets emptied.
