GAM API support multiple creative sizes for video?

[MelissaD]

Hi,

I am trying to send over multiple video sizes for creative level targeting. Each video size should be it's own placeholder with it's own creative size targeting applied. However, sizes are being sent with one placeholder and the remaining sizes as companions. This only occurs for Video lines, Display works as expected.

Does the API support multiple video sizes for creative level targeting?

Example - I want it to look like attached GAM_A screenshot but it looks like GAM_B.

Thank you!

• Network code
