Auto-tag drives between categories of locations

I am using the record of drives to document business vs personal trips for tax deduction purposes.  In Australia, trips between work locations are deductible (as is the subsequent return home, but the rule for this might be too complicated).  Currently I use the same icon for places of work, and a different icon for the central office.  Would you consider allowing auto-tag rules based on place icon (as a surrogate for place category) rather than specific locations?
