Monovar with single BAM file

Question

[gnomee]

I am trying to do SNV calling with single cell data. For this, I wanted to apply Monovar to the data that I previously aligned using cellranger. Is there a way to use Monovar without splitting the cellranger BAM output file into BAMs for each individual cell, so instead just using the original BAM with the cell barcodes annotated as tags for each read?
