I have an expresssion like:

```
ex:= \int{ \partial_{0}{a} \partial_{0}{a}
+ a \partial_{0}{\partial_{0}{a}}}{x};
```

which I want to show is zero when either term is integrated by parts

However it seems the basic command does both terms

`integrate_by_parts(_, $a$, deep=True);`

Gives

\begin{equation}{}\int \left(-\partial_{0}\left(\partial_{0}{a}\right) a-\partial_{0}{a} \partial_{0}{a}\right){\rm d}x\end{equation}

Which is true, but not really want I want. Is there a way to choose a specific term to IBP.

Thanks
