London 2012 gold medallist Katherine Grainger and Vicky Thornley have reached the final of the World Rowing Cup in their re-established women's double scull partnership.
Their cause will be helped after they reached Sunday's final in Poznan.
They qualified in second place from the repechages, behind New Zealand.
Grainger, 40, and Thornley, 28, had led before being caught on the line by the Kiwis.
"We were much better in the first half of the race today - that's a step-up from the heats yesterday," said Wales' Thornley.
"We have stuff to work on but now we can enjoy the final and see how much speed we can get out of the boat".
Grainger and Thornley had dissolved their double scull partnership in May to focus on earning spots in the larger boat but they were not on the list of 43 names announced by Team GB on 9 June.
Should she win a medal at her fifth Games in Rio, Grainger would become Britain's most decorated female Olympian, having also won silver medals in Sydney, Athens and Beijing.
British Rowing performance director Sir David Tanner said it was his "confident intention" to get them back into the doubles boat.
Great Britain will have plenty of medal prospects on the final day of competition in Poland, as London 2012 Olympic bronze medallist Alan Campbell won his men's single scull semi-final, while Alan Sinclair and Stewart Innes won their men's pair semi.
Their rivals for Rio selection, Nathaniel Reilly O'Donnell and Mat Tarrant, were second in the other semi-final, which was won by the Olympic and world champions New Zealand.
Britain's two lightweight men's Olympic boats were in repechage action and booked their places for Sunday with two second-placed finishes.
Will Fletcher and Richard Chambers were narrowly beaten by Ireland in the men's double sculls semi-final, while Chris Bartley, Mark Aldred, Jono Clegg and Peter Chambers were second to the French in the men's four.
Rachel Morris won gold in the women's para-rowing single scull, while Oliver Cook, Callum McBrierty and cox Henry Fieldman took the title in the coxed pair.
World champions Sam Scrimgeour and Joel Cassells maintained their unbeaten record in the lightweight men's pair.
