Force processing of fundamental data for backtest / signal test

Is there currently a way to either precompile or force the testers to compile/download fundamental field histories?
At the moment the best I can come up with is to open a watchlist, put a view with the datafield on it and then auto cycle through the watchlist to populate the data.
Currently unsure if that is going to have to happen every time I open optuma, and also doesn’t include historical members of a list.

If I don’t manually compile/download like this, the field just pretty much gets ignored in the testers.
