Saved model files with numbered extensions?

Hi everyone!  I used Solidworks at my last job, and I am still relatively new to using Creo Parametrics.

I was wondering if there is some setting that will allow the model file to be overwritten when saved rather than adding another saved file to the folder with a progressing number extension?  I end up having tons of the files for 1 part/assembly because I save my work often.

Can anyone help me out here, PLEASE??

Thanks!
