Arbitary charge per bunch with arbitary macro-particles per bunch?

Hi all,
I'm scratching my head how to do this. Take for instance if we want to run hybrid mode. Right now, if we want to run a bunch with a greater charge, we have to run more particles (with CHARGE, PER_PARTICLE=1). Clearly we are concerned with the running of the single bunch with greater charge, but wish to know how long range wake effects affect the dynamics. At a minimum we would like to run every bunch with the minimum number of particles required (just with different charge specified). Perhaps a little safer still would be to specify more particles for the studied bunch in question. Afterall, the long range effects aren't as strong meaning that the exact shape and position of the other bunches isn't as essential to the calculations.
