Basis alternative to CFG3

Dear community,

out of curiosity - these days i needed to do an SLG1 search, and it struck me that in SLG1 selection is done only on log object/subobject class, and there are no selection options to restrict by a certain message class/number.

This is possible in transaction CFG3, however CFG3 theoretically is available only on SCM/APO systems, one could expect such a feature though in the generic SLG1 functionality. (As i am working with such one, i have access to CFG3 and it is just fine ).

Is there out there a BASIS transaction, similar to SLG1 that covers that? And is then available in all kinds of systems, not only SCM.
