A ball seat is integrated with a movable biased sleeve. Sleeve movement against its bias moves a diverter from a position outside the through passage to a position across the main passage such that any balls that drop down will be directed by the diverter into an annular retention volume. In treatment of the formation for fluid loss the movement of a seat with the seated ball opens lateral ports for delivery of sealing material and moves the diverter. Smaller balls are then introduced to close lateral ports above the seated ball so pressure can be built to shift the sleeve and extrude the first ball. Once the seated ball blows through, the smaller balls come through the seat and are all diverted to an annular capture volume. The device is resettable for multiple operations. Fluid flow cessation closes lateral ports and opens a through passage retracting the diverter.
