Are there any news concerning custom font family for circos.genomicLabels?

[lokapal]

First of all, thanks for very good package, although it is underdocumented still (at least, as it seems to me).

The question is - are there any news/progress concerning custom font family/font names for circos.genomicLabels? Could it be hardcoded if not made by option? I'd like to use for those labels Roboto Condensed https://fonts.google.com/specimen/Roboto+Condensed free fonts. It's especially useful for labeling the genes that doesn't have symbol names, so I have to use Ensemble IDs like ENSG00000287404.
