Out of the box the drilldown (toggle visibility action) icon is with fixed position.
In order to change the icon position our suggestion is in the place of the Textbox toggle item to insert a Panel. Then add within the panel item another panel for toggle visibility action (drilldown) and a textbox for the cell text (the previously used textbox). This way you can control the drilldown icon exact position within the main panel item.
