selectable start image

Hello,

After trying several sliders, I ended up with Slider by Supsystic.
It does everything I want, except one thing : I want to use the same slider with the same images on different post, but they should start with a different image.

Example : I have a blog about the renovation of an old house and there are photos from, 2011, 2014 and 2016 that shows the object at a different stages of renovation. Each photo has its own post. With the slider I can simply show the difference between the situation in 2011 and 2014.

I can put links to go to the post belonging to the photo. However, on the post of 2014, I want to start the slider with the photo of 2014 and on the post of 2011 it must start with the photo of 2011.

I was thinking about an extra option, like :
[supsystic-slider id=1 position="center" start="2"]

then it should starts with the second photo.
on another page I will use the same but with a different start image, like :
[supsystic-slider id=1 position="center" start="3"]

It is possible for you to add such an option ?

Many thanks
