LAS PRJ file

[Jeff_VanEtten]

Good afternoon. 

I have a folder full of LAS files (circa 400+) all in the same projection.  Is there a way to create a default one that would be used by all of these in ArcGIS Pro similar to CAD files with the ESRI_CAD.PRJ projection file?  Would be useful if I could set one to say ESRI_LAS.PRJ and this set all of these files at once...rather than having to do each one at time.

Thanks
Jeff
