Hourly rate defaults

Okay so I work for a paving company and my hourly rate changes from day to day depending upon whether I'm on a state job/TDOT and what I am doing on that state job, i.e Class A,B,C,D operator or skilled laborer/unskilled laborers. It would be great to be able to select which ones I am doing daily and have it auto calculated into my weekly pay. Otherwise great app.
