  Earlier, we suggested the "reload" concept of the polarimetric reverberation
mapping of active galactic nuclei (AGN), proposed for the first time more than
10 years ago. We have successfully tested this approach of reverberation
mapping of the broad emission line on the galaxy Mrk 6. It was shown that such
an idea allows one to look at the AGN central parsec structure literally in a
new light. However, the method originally assumed the use of
spectropolarimetric observations, expensive in terms of telescope time, and
implemented on rare large telescopes. Currently, we propose an adaptation of
the polarimetric reverberation mapping of broad lines in medium-band filters
following the idea of the photometric reverberation mapping, when filters are
selected so that their bandwidth is oriented to the broad line and the
surrounding continuum near. In this paper, we present the progress status of
such monitoring conducted jointly at the Special astrophysical observatory and
Asiago Cima Ekar observatory (OAPd/INAF) with support from Rozhen National
Astronomical Observatory (NAO), some first results for the most frequently
observed AGNs Mrk 335, Mrk 509, and Mrk 817, and the discussion of the future
perspectives of the campaign.
