Regrid without specifying lat and long

I’m using harp to regrid a series of netcdf files. In the past I have used bin_spatial with lat and long dimensions to regrid. Is there a way to regrid to a 0.01 resolution WITHOUT specifying lat and long? I want to have a consistent resolution without bothering with the lat, long and step parameters of the bin spatial.

Not using HARP itself. You can write your own wrapper function around it (in e.g. python). Then you only have to implement the lat/lon/step calculations once.
