Is it possible to update one .mif file instead of the all set (to speed-up)

Hello,

I use the update memory initialization file from the quartus processing menu, then the assembler to generate a new sof.

As I have a big flash memory, it takes a while to update the mifs.

Is it possible to only update the mif of one ROM block and not the all set?

If yes, what is the quartus command line to do that?

Kind Regards,

Alex.
