Hi Val,
on the carousel you can only click left and right or grab the images and slide them.
But there is no official way yet to also think the carousel or the content inside.
Somewhere you need to add a see more button.
The button could also appear only if you hover with your mouse above the bottom part of the image for example.
But to achieve this you need to know the basics of jQuery.
But thank you for your input with adding a slideshow as a project thumbnail. Until this is implemented you need to find a workaround like I described above.
Have a good day and let me know if you have questions!
Best!
Marius
