D3300, file labeling differs in one photoshoot: _DSC5202 and next can be DSC_5203, can I change it?

D3300, file labeling differs in one photoshoot: labeling can be: _DSC5202 and next can be DSC_5203, difference is only in the placement of sign( _ ) can I change it? I want it to be one way or another, so when Im viewing pictures, they do go in order, not mixed.

Thank You.
