Vascular Diastolic pressure and Stroke volume

I thought that given a constant HR and TPR, if you increase SV systolic P increases accordingly and because you have the same time for blood runoff during diastole but a higher starting amount in the aorta due to the higher SV. Then after some of the blood runs off during diastole you would have a higher diastolic P because more would remain in the aorta than before. Is this correct?
