<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
This function is only needed if auxiliary data needs to be passed to fine grids while grid sequencing
<P>
If this function is called multiple times, the hooks will be run in the order they are added.
<P>
This function is currently not available from Fortran.
