Hi , tnx for yout great tool , there is a little optimization that help greatly to users , when we save powerpoint ourselves within powerpoint itself it automatically remove redundant files ( maby it compare them with hash ) and save it with lesser file size , if our root template contains multiple redundant image file I export with pptx-automizer then again open with powerpoint and save it again , it make file size half , could this library do this optimization itself ?
