Template 1 frame length into similar template

Adding a template one frame length into a template with similar element contents:

In Animate 1, when you add a 1 frame length template into a similar template (with several frames) located in timeline and apply paste special with “paste all frames of the movie” enabled, the exposure is not showed.
Then the trick: apply the paste special in the template 1-frame, without selecting “paste all frames of the movie” and the exposure is done. Unexpected but effective mode!

Yoryo.
