DOLIBARR change mailing settings and fix old module with error at list of thirds columns showed

I need to change the dolibarr mailing to add "contacts by third-agent" and/or to add "contacts by third-postal code" and I have just upgrade the version to 7.0.1 from 4.0.0 and ALSO with the upgrade of the older works, that now they do NOT work with the new Dolibarr... TO-DO: 1.-Fix the old works: In the "list of thirds" the column "Poligono" do not show results, neither order field. nor search, etc 2.- In the "list of thirds" : add "agent/s" as a column that shows all the agents/users of the "third" 3.-In "Utility-Emailings": "Destinatarios" (senders?).....Add a filter by "contacts of thirds that belong to AGENT" (allways less the contacts that do not want to receive mass-mailings) 4.-In "Utility-Emailings": "Destinatarios" (senders?).....Add a filter by "contacts of thirds that belong to POSTAL CODE" (allways less the contacts that do not want to receive mass-mailings) 5.- In "Utility-Emailings": "Destinatarios" (senders?).....Add a filter by "contacts of thirds that belong to PROVINCE" (allways less the contacts that do not want to receive mass-mailings) 6.- In "Utility-Emailings": "Destinatarios" (senders?).....Is it possible to do "filters" to TAKE OUT contacts already chosen that meet criterias: agent, postal code, providence, categories, etc
