Can I design one item cross several factors in lavaan model?

[ss xx]

modificationindices() indicate item `q21` may affect several factors `f5`,`f6`,`f1`,`f4` as below: 

     lhs op rhs     mi      epc
763   f5 =~ q21 980.89 -0.73431
815   f6 =~ q21 980.41 -0.76884
818   f6 =~ q50 976.38  0.75211
545   f1 =~ q21 921.43 -1.11413
710   f4 =~ q21 887.53 -0.61507

Can I design `q21` cross these factors in model,such as: 

lavaan_model<-'
f1=~q10+q12+q22+q21
f2=~q11+q20+q24+q26
f3=~q19+q21+q25+q52
f4=~q04+q17+q18+q45+q21
f5=~q02+q50+q13+q14+q21
f6=~q06+q15+q34+q43+q21
