Stretching bands

My team has an idea that would require string, but since VEX IQ does not have a string ‘part,’ we can make due by using the pulley bands. To do so, we would need to stretch the bands to get rid of any potential elasticity. I understand that the rules say that you can not alter parts by doing things such as cutting or melting. Would this be deemed as breaking the rules, considering that the bands could naturally lose their elasticity very easily from overuse in a normal circumstance? We do not plan to cut the bands, just stretch them and tie them together to make a longer string of sorts, but before we do so, we would like a verdict on whether or not this is acceptable. Thanks!

This would not be considered a modification and would be legal.
