Mediation-moderation efficient coding

When setting up a regression model, if the outcome variable is a brain image and the predictor variables are not brain images, then a rapid version of regression can be used. The design matrix may inverted once and then repeatedly multiplied by the data at each Voxel.
I wonder if bootstrapping repeatedly can take advantage of the premultiplication routine used to speed up regression with brain imaging.
