Can we include multiple DCRs in one TPL ?1) Which DCr to to use to preview the page, generated by TPL ?2) TPL is included in presentation folder of a datatype. If we want to inclde multiple DCRs of different datatypes displayed by a single TPL, do we need to include this TPL in all the datatype presentation folders ?3) Or do we have to include different datatype TPLs in one TPL in order to display multiple DCRs ?4) How does the mapping work , when I preview the DCR ? When a particular DCR is previewed, tpl of that datatype is invoked. When I include different child TPLs in one parent TPl, and when parent TPL is invoked, it will invoke all child TPLs included in it. But in the data folder child TPL datatypes , if there are many DCRs, which DCR will be selected for the display , when this child TPL is invoked by the parent TPL ?thanks
