No, but there are several workarounds and you can choose one that you think works the best for your tree.
If you're not including the biological family, then you can just put Adoptive Child at the end of their surname. If you are, however, a few workarounds that I've seen is to add a fake partner to the adopted child and name it something along the lines of "focus person's adoptive/biological family) and add the adoptive/biological (whichever type of family you chose) parents & siblings to that family. For adoptive parents, do the same thing as before but add the biological/adoptive (again, whichever you chose) children to that partner.
Another one I thought of is to have two fake parents each named "Biological Family" and "Adoptive Family" and go on from there. Biological siblings that aren't adopted by the same parents can be the "sibling" of the "Biological Family" parent. Biological siblings that were adopted by the same parents can be added as the adoptive child's sibling, no workaround needed. Adoptive siblings can be the "sibling" of the "Adoptive Family" parent. The biological parents of the focus person can be "Biological Family"'s parents and the adoptive parents of the focus person can be "Adoptive Family"'s parents. Of course, this workaround can make the tree look strange, so this might be recommended for focus people who don't have that much of an extended family.
