PYNQ Microblaze Memory

I read that "The local PYNQ MicroBlaze memory is 64KB of shared data and instruction memory. " and was wondering how I could change that. I am using the Xilinx Zynq UltraScale+ MPSoC ZCU104 board which has a couple of MB of block ram and my microblaze program keeps overwhelming my ram. Is there some way I could change that

If you open the design, find the right MicroBlaze/BRAM, you can reconfigure the memory sizes.
Are you using the SDK flow to generate your application(s)?
