How to Import .MAT(Matlab) data as Signal (not Data Series)

I have separate vectors for time and data in Matlab.

When this is imported from a Mat file to flexpro, it is imported as Data Series.

I would like to import it as Signal (time and data embedded in same signal).

I tried creating structure, cell and 2xN array in Matlab, but flexpro always imports them as two separate data series.

Is there a template explaining how data should be arranged in matlab, such that it is recognized by Flexpro and imported as Signal instead of Data series?
