Posts and string to extend the net's height

[webbeing]

Hello,

Does anyone happen to know where I can find a tennis training equipment consists of two posts (that can quickly attached to existing net's posts) and a yellow string (stringing across the two "new" posts) to extend the height of the net?

The idea is to practice hitting topspin shot much higher over the net to drop deep near the baseline. THanks.

two sticks, some zip ties and some string?
