Slider & Thumbnail mode combined

Dear GT3 team,

I’m trying to find a WordPress solution for a Squarespace-like gallery behaviour.
I’m talking about the Wells template (example: https://www.mpkelley.com),
where the page lands on an image slider mode, but it’s also possible to switch to the Thumbnail grid and back!
Can GT3 Gallery do something like that?
Thanks in advance,
Sasha
