Miroslav Tremolo problems in notion sle and logic

Hi guys, new to the forum here. I'm having trouble keeping the tremolo constant between bars in logic and notion sle.
For example, I have 5 bars of tremolo violins and violas, if I score them as a breve across each of the whole 5 bars then there is a gap between the bars as it seems to restart the tremolo on each new bar. If I put a tie on the notes then the tremolo fades at the end of the second bar and the remaining 3 bars are silent.
The same applies in logic with the piano roll and the score functions.
Is there a way to keep the tremolo constant and seamless between the bars using notion and or Logic?
Thanks, Stan.
