To do that, you would actually need to work at a deeper level, and alter the programming of the EBB itself, since it presently does not have any facility to work from an off-board stored file. It is certainly possible to reprogram the EBB– its source code is available, as are compilers.
The EBB does have the facility to work from a file stored in its onboard memory — there are actually two files stored there — but it does not have the ability to connect directly to an SD card. And, the computer is not necessarily something that can’t be brought along with you. For example, a Raspberry Pi could easily fit in your pocket.
