This is a re-run of my large conjoined thread - https://rocket.unrealengine.com/questions/1841/feedback-my-next-round-of-contenteditor-feedbac- broken up in different threads as per request of Alexander.
When importing SM, it pops up the import dialog for each mesh. There is no Import All. I just imported 50 meshes, and had to press “ok” 50 times in a row.
agreed. just happened the same to me 
Hi Sjoerd,
Thank you for your report, I added a detailed report about it to our feedback database and referenced this post. I will make sure this gets looked into quickly.

Hi
Was just wondering of there is any further response to this problem, (I’ve been having to do the same all week) as it isn’t just Static Meshes but Textures as well.
Thanks
Dan
We’ve added import all support and it will be available in the next release.
