Yes you can get delays of micro seconds by using a C code block and the following.
//Delay for multiples of 1us
delay_us(1); //You can replace the 1 with any number up to 255 to acheive longer delays.
One problem with the last command is that it will not work at certain frequencies due to problems scaling the delay value correctly. To remove this problem you can use this command.
//Delay for multiples of 10us
delay_10us(1); //Again you can replace the 1 for longer delays.
