Dynamic SLD Name and Title using Geosever

Question

We are trying to make dynamic sld where color pallets will be created according to env parameter passed to sld, and get Legend for the same using getLegendGraphichs of geoserver but with no success, is it possible to get Name and Title section of sld also get updated dynamically according to env parameters, if not is there other alternatives?

Our thought is that if some how we are passing env parameter to title then we will get the updated title of legend

This the env string we are passing to openlayers wms request ENV=class1:38.81;class2:42.82;class3:46.82;class4:50.83;class5:54.83;class6:58.84;class7:62.84
