Since the implementation of instruments that allow us to obtain multi-object spectroscopy, this technique has been progressively improved and surpassed, and it is now possible to get 3D information on a variety of astrophysical objects. However, specifically in the area of extragalactic globular cluster systems, several years ago the possibility of taking advantage of the multi-object characteristic of spectrographs was identified as a tool to recover valuable information about those galaxies in which spectra of its globular clusters (GCs) have been obtained. That is, to study the properties of the stellar component and the ionized gas (when present) of a galaxy, as a plus from the study of its stellar clusters. Here we present an example focused on the case of NGC 1316 that, for several reasons (young GCs, tidal tails, debris, etc.), represents an object of interest to test this technique.
