description A downhole tool subassembly has an outer sleeve with a first set of apertures extending from an inner bore of the outer sleeve. An intermediate sleeve positioned is within the outer sleeve and defines an intermediate flow path extending from an inner bore of the intermediate sleeve to a cavity formed between the uphole portion of the outer sleeve and the downhole portion of the intermediate sleeve. An inner sleeve is positioned within the intermediate sleeve and has an external sealing portion that restricts flow across the intermediate flow path when the downhole tool is in a first configuration.
