from the report?  Not that I am aware of.  CR reads data, and in rare cases can be made to write data(not something that I am in support of) but creating an index...   I suppose it is possible, but my gut reaction is to not do it... there are several issues and I don't know how good CR is at handling SQL...  CR is basically set up to simple select statements, and I don't know if adding/dropping/checking indexes qualifies as being in the realm of CR...after all, there isn't really any error handling, so when something goes wrong, either you won't know it or CR will close from the error...at least that is my best guess.
