Showhide inside another Showhide

Hi I was wondering if I could have a show and hide inside another show and hide:
The code I’m using is this but it doesn’t do what I’m trying:

[showhide type="2016" more_text="2016 " less_text="2016 -" hidden="yes"]
[showhide type="term1" more_text="Term 1 +" less_text="Term 1 -" hidden="yes"]
<ul>
<li><a href="https://######" target="new">Biological Sciences</a></li>
<li><a href="https://######">Biological sciences stage 3</a></li>
<li><a href="https://######" target="_blank">Biological sciences stage 4 </a></li>
</ul>
[/showhide]
[/showhide]

Any help is much appreciated.
