Connecting boards in a multi-level hierachy

Looking for a way to reflect the Objective/Goals/Strategy/Measures organisation strategy tool that can be used to link low level projects(measures) to organisational objectives. I want to be able to aggregate project status and timelines as you ascend the ladder from multiple projects supporting a sub-strat, to several sub-strats supporting a strat, to several strats supporting a goal, to several goals supporting an objective. Connect/mirror works brilliantly for two levels but not beyond. The OGSM template is almost standard now in organisations so I can’t be the first Monday user faced with this challenge. I not there are multiple apps out there that roll up data across boards. How have others solved this conundrum? Would be very interested to see how others have solved it.
