Hello list, is there a better way to interlace overbraces and underbraces like this?

\starttext These are the expressions to combine:

$$\overbrace{a+b+c}+d \quad a+\underbrace{b+c+d}$$

This is the desired result:

$$\overbrace{a+b+c}+d \kern-16mm\underbrace{\hbox to 15mm{ }}$$

\blank {\tfx(the underbrace should move down a little more)} \stoptext
