Importing Seqvence of images in to AME lead to strange behaviour

After upgrading AME from 2014 to 2017 dragging image sequence in to AME leads to different behavior.

Now it asks me if i want to import each image separately or "stitch" them . Upon choosing latter AME creates one rendering node with all images

however resulting output would make each image not equal one frame (which is only logical interpretation of image sequence) but instead each image in the sequence would last for something like a second - making it some kind of slideshow.

How can i  achieve a result (which was previously a default) where each image in a sequence i import would be interpreted as ONLY ONE frame of resulting render?

In case it's not clear -- image sequences (JPG, TGA , PNG DXF) is most common way to output animated materials in all VFX and animation related industries.
I really not sure who would benefit from transforming frame by frame sequence in some kind of slideshows - but i'm certain it wouldn't be one of the many video VFX and animation professionals using adobe suite.
