allocation percentages of expenses for STR within my residence

Hello

I have a short term rental at my primary residence.  When the CPA did my returns previously, it shows 16,5% depreciation of the initial cost of the property and the points (based on square footage).  But we allocated 50% of the utilities to the rental, and 100% of one of the insurance policies (which was just for the rental).  Will I be able to allocate different expenses by different percentages with this software?  Or am I going to be limited to allocating every expense by the 16,5%?,
