At present "combined texts" cannot be used in the primary pane. They are only available in a parallel pane. The Search text must be a single language and a single canon. The primary pane need not be in English, but it needs to span the entire range of whichever texts you want to combine in the parallel pane.
We considered trying to produce a combined text (your LXX and GNT combination was the one we discussed), but the tagging systems are just too different. We also figured there would be other issues. Which GNT? Which LXX? Why not Apostolic Fathers and a GNT? Or some other combination? How would we have to modify the analytics to accommodate these sorts of searches?
For now, the easiest way to do this is to set up a search in one tab (say NA28-T), then place the LXX in another tab and use the [LINK ?] command to tied the two searches together. What ever Search argument you place in the first pane will also be executed in the second pane. Each will have its own set of analytics.
