How can I measure the channel power of multiple channels at once?

I own a BB60D product.

I currently work in terrestrial broadcasting.

I would like to measure the channel power of multiple channels simultaneously in the field. How should I proceed?

For example, I intend to measure the channel power of the following wireless channels in the field:

=========================

CH # | Center Freq | BW

==========================

14 | 473MHz | 6MHz

15 | 479MHz | 6MHz

16 | 485MHz | 6MHz

17 | 491MHz | 6MHz

18 | 497MHz | 6MHz

.

.

.

.

51 | 698MHz | 6MHz

Currently, I am measuring the channel power for each channel individually, but it takes too long. The other equipment I used previously had a "Channel Scanner" function that made it possible to measure the channel power of all channels at once.

How can I measure the channel power of all channels simultaneously on the BB60D as well?
