character limit for Custom instructions (limits world builders)

i know that custom instructions is the old system which is fine but the current character limit prevents world buildings from pushing full featured context blocks without splitting it into multiple Custom instructions. its just one much neater in the context blocks, also after splitting up the instructions Franz doesn’t always understand it the same way. forcing me to add extra instructions to make it work. preferably a 1500 character limit for Custom instructions so it fits perfectly when converted into a context block.
