How to control level sequence with external file?(CSV)

Hi,
I want to link the time values from my level sequence to an external excel file like CSV (Comma-separated values - Wikipedia).
I found the way to get value from a CSV file but can’t link it to a blueprint that get my “level_sequence”.

Anyone could explain me how can I edit my level sequencer with blueprints?

Thnaks a lot :wink:
