Adding hourly top of search impression share (TOS IS) into AMS?

[jiadongpg]

TOS IS is available in the Amazon Ads API, but was wondering if there are plans to add the same hourly metric into AMS as well?

Also, am I able to confirm what exactly is considered as "top of search" in the "top of search impression share" metric? Is there a number of paid slots on top that Amazon considers to classify something as "top of search".

Thx.
