new pipework database in netsys calculation

Is there a way of adding new pipework database to netsys heating/water services calculations? I have a series of calcs to carry out on heating circuits made of Uponor MLCP pipes. There is a database for Uponor Unipipe which is the predecessor of the MLCP press, but the default pipe fittings are cast iron rather then uponor press fittings. The later have more pressure drop across them...
